> nobody drives a bike for 5 hours straight Plenty of people do, actually. When I was a bit more overweight and trying to lose it, I used to go for 4-6h long rides around London in the weekends, and 3-4h long rides in the evenings after work. Lots of non-professional cyclists go on cycle tours where they can ride for 10h or more for several days. On top of that, 1h-1h30min long rides to and from work and other places were quite common as they are for many cyclists, and I suspect this is about the same for drivers in big cities.
